the point of the joke wasnt that he was a prostitute, it was a part of it but it wasn't the point. The point was that the daughter tried to get her father to spend an hour with her cutely and the dad obviously agrees. But then the mom tried to do the same thing but naughtily.

Wow honestly cant believe I got thumbed down into oblivion...it's amazingly sad that someone who just said "lol he is basically a prostitute of his family" actually got 332 thumbs for saying the most obvious thing about the comic.

Actually the joke is that the daughter wanted to spend time with her dad, but her mom wants to spend time doing.......well, adult things with her dad. So the joke isn't that he is a prostitute, but that he's being used for different things. I'm not that good at explaining **** like this, so I hope your understand it.

It seems kinda poorly translated, maybe it was a regional thing where 50 dollars would be worth a lot less, or the currency wasn't changed to fit the English translation.
Or the dad's a ******* drug dealer idk.
